    28  * @summary converted from VM Testbase nsk/jdb/down/down002.

    29  * VM Testbase keywords: [jpda, jdb]

    30  * VM Testbase readme:

    31  * DECSRIPTION

    32  *  This tests the jdb 'down' command. The test sets a breakpoint

    33  *  at 'func5' method in debugged 'nsk.jdb.down.down002a' class and then

    34  *  runs the debugee.  Once, an execution suspends at 'func5' method,

    35  *  the 'down' command is issued to the debugger several times.

    36  *  The output is processed by counting the number of times

    37  *  each method name appears in the stack trace. The test passes

    38  *  if the obtained count matches the expected one.

    39  * COMMENTS

    40  *  This test functionally equals to nsk/jdb/down/down001 test and

    41  *  replaces it.
